Electric vehicles, capable of powering themselves using only the sun’s rays as fuel for propulsion across hundreds and thousands of miles.

IMPRESSIVE: The three-storey beer bong is a sight to behold

And now, a 40ft beer bong, stretching down the face of a three-storey building capable of delivering 2.5 cans of beer in less than three seconds.

What a time to be alive.

Writers at popular food blog Foodbeast created the monster structure, for no particular reason other than the glory of achieving something brilliantly pointless, showcasing its function in an amusing 40 second video.

They priced the home-made job at $80 (£60), including all the necessary tools and equipment to replicate the giant chug tube – a reasonable price if you happen to have access to the roof of a three-storey building.

“All I can say is, my boy Sean was not ready for the speed at which the beer was flowing through his body but thankfully, he's still alive, somehow,” Foodbeast writer Isai Rocha posted on the blog.
